ATLESH-1M

Radiometer of radon daughters "ATLESH-1M"Radiometer "ATLESH-1M" is designed for express measurements of equivalent equilibrium volumetric activity (EEVA) of radon in air of dwelling and working premises.Radiometer can be used for:

Radiometer "ATLESH-1M" applies express method of measurement of equivalent equilibrium volumetric activity of radon by means of pumping high volume of air through analytical filter. Such method increases sensitivity of instrument, shortens measurement time and ensures reliability of obtained results.
